Stephen Hawking is either sharing some of his brilliant insight or he’s been watching the TV series V but he says we should avoid meeting aliens at all costs.
The brilliant scientist theorizes in a new documentary series that it’s very likely that life has evolved on another planet but that it’s also more than likely that those life forms are relatively simple animals. He believes that if they’re going on a quest to another world, they have used up the resources on their planet (just look at the way we are heading!) and will want to find another host to plunder. He cites Christopher Columbus as an example. When Chris and his colleagues got to the new world it “didn’t turn out very well for the Native Americans.”
In conclusion, aliens are more like the murderous liars in Mars Attacks than sweet like homesick E.T. Don’t invite one home because he’ll probably eat everything in your house including your pets and possibly your relatives.
